$C^0$ Approximations of foliations

Geometric Topology 2018-03-16 v2

Abstract

Suppose that F\mathcal F is a transversely oriented, codimension one foliation of a connected, closed, oriented 3-manifold. Suppose also that F\mathcal F has continuous tangent plane field and is {\sl taut}; that is, closed smooth transversals to F\mathcal F pass through every point of MM. We show that if F\mathcal F is not the product foliation S1×S2S^1\times S^2, then F\mathcal F can be C0C^0 approximated by weakly symplectically fillable, universally tight, contact structures. This extends work of Eliashberg-Thurston on approximations of taut, transversely oriented C2C^2 foliations to the class of foliations that often arise in branched surface constructions of foliations. This allows applications of contact topology and Floer theory beyond the category of C2C^2 foliated spaces.
